Application filed August 6, 1919. Serial No. 315,588.

To all 20710171 2 2. may concern:

Be it known that I, ADDISON E. AnousrlNE, residing at I-lackenseck, inthe county of Bergen and State of New Jersey, have invented certain newand useful l n'rprovemerits in Bodily llemovable Creasing and lioldingBox Mechanism for Envelope-Maleing Machines, of which the following is aspecification.

This invention relates to a creasing and folding box mechanism forenvelope-mahmg machines, and an obl ect of the invention is to provide acreasing and folding box 1 mechanism so constructed and so related toentity which is bodily attachable and removable as such.

A further object of the invention is to provide means whereby thecreasing and folding box entity may be quickly and accurately attachedin position within the machine, or removed from the machine, in theevent of necessity for repairs or for other purposes. a i y i Otherobjects and aims of the invention, more or less specific than thosereferred to above, will be in part obvious and in part pointed out inthe course of the following description of the elements, combinations,arrangements of parts and applications of principles, constituting theinvention; and

the scope of protection contemplated will be indicated in the appendedclaims.

In the accompanying drawings which are to be takenas a part of thisspecification,

and in which I haveshown merely a preferred form of embodiment of theinven taken substantially upon the plane of line 1V of Fig. 3.

Referring to the drawings for describing n detail the structure which isillustrated therein, the reference character L indicates the supportingtable upon which the creas ng. and folding box mechanism is supported.

This table is formed with an opening 1 therein. for receiving a portionof the creasng and folding box'mechanism, said openmg being providedwith an upwardly facing ledge 2 formed in its side walls. 7

The creasing and folding box mechanism includes a base plate G and a topplate ll. These plates G and H are rigidly connected together bysuitable standards 3 and 4. The top plate H constitutes the creasing boxof the machine, and the base plate G can ries a trap The various otherelements, such as the conveyor 6, the front dagger 7. the rear dagger 8and the folders 9, related to the creasing and folding operations, aswill be readily understood by those familiar with this class ofinventions, are all carried by the two plates and all combine to make upthe creasing and folding boxentity which is bodily removable from thetable L.

The plate G is of a size to -fit snugly into the openingl in apositio-nresting upon the upper surface of the ledge 2. At the rear of theopening 1 the upper surface of the table is depressed to provide asurface 10 standing at the same level as the upper surface of the ledge2, the surface 10 constituting in effect an extension of the ledge 2.When the plate G is in operative position, as in Fig. 1, its rearportion, as 11, overlies and rests upon the surface 10 while the forwardedge, asxl2, of the plate fits beneath a clip 13 formed rigidly with, orfixed to the upper surface of the table I, overhanging a portion of theledge 2, the clip 13 serving with the ledge 2 to provide a recess 14 forsnugly receiving the portion 12 of the plate Gr therein. Any suitableholding means, such as the screws or bolts 15 may be extended thru theportion 11 of the plate G and into engagement with threaded holes 16which are formed in the table L.

By this means the plate G is rigidly held in position and yet may bequickly and easily removed by simply removing the screws 15. While thescrews are in place, of course, it is impossiblefor the portion 12 ofthe plate to disengage from the recess 11,

1 to the actual removal of the entity, the drive links, or the like, as17, for the different moving elements of the creasing and folding boxmechanism should be discoi'inerted, as seen by comparison of Figs. 1 and2.

In this connection it should be noted that the'inanner of connecting themembers 1? with the moving parts of the creasing and folding boxmechanism, may, if desired, be made so as to be readily detachable, oreven so that by proper manipulation they will not hinder removal of theentity. Particular attention is directed, for instance, to the mannerillustrated in which the driving connection is'made with the frontdagger T of the entity, such connection including simply an open endedslot 18 within which is placed a pin 19 for operating the dagger, theparts being arranged so that the pin will. simply move out of the end ofthe slot when the entity is lifted away.

It will be understood that in use the creas ing and folding boxmechanism is dispo ed adjacent to a pile, as 20, of envelope blanks, andthat the blanks are picked up one at a time by suitable pickers 21 andconveyed to the creasing box by the conveyer 6, that when a blank is inposition over the creasing box a plunger 22 descends and forces theblank downwardly between thefolders, whereupon the folders 9 operate tofold over the flaps of the envelope, and that finally the trap 5 swingsdownwardly to deliver the envelope.

Heretofore the various parts of the creasing and folding box mechanismhave been mounted almost without regard to the question of accessibilityfor the making of repairs, but by the present invention it will beappreciated that in making up all of the parts of this creasing andfolding box mech anism as a single entity capable of being easilyinserted into the machine or removed at will, an operator can readilylift out the entity and replace it at will, meanwhile making any repairsor adjustments required.

As many changes could be made in this construction -without departingfrom the scope of the following claims, it is intended that all mattercontained in the above description, or shown in the accompanying I claimas new and desire to secure by lactters Patent is:

l. A creasing and folding box mechanism for envelope-making machinescomprising a creasing box, front and back dagger mechanisms, flapfolders, a trap, and means connecting all said parts together to behandled as a single entity which may be inserted into or removed fromappointed position in an envelope-making machine.

2. In an envelope-making machine, a creasing and folding-box mechanismand a trap device all constructed as a. single ontity adapted to beinserted into or removed from the m chine at will, and means where by todetachably retain said entity in operative position within the machine.

3. In an envelope-making machine, a creasing and folding-box mechanismall constructed as a single entity adapted to he inserted into orremoved from the machine at will, and means whereby to dctachably retainsaid entity in operative position within the machine.

4:. In an envelope-making machine comprising a table having an openingvertically theretlnru, a creasing and folding-box mechanism and a trapdevice all constructed as a single entity adapted to be inserted into orremoved from said opening, and means whereby to detachably retain saidentity in operative position within said opening.

5. In an envelope-making machine. a creasing box, flap foldersassociated therewith, front and back dagger mechai'iismsa trap, frameparts connecting all of said ele ments together to constitute them as asingle entity which may be inserted into or removed from the machine atwill. and means whereby to detachably retain said entity in operativeposition within the machine.

6. In an envelope-making machine. a creasing and folding-box mechanismcomprising upper and lower plates, the upper plate having an openingtherethru. wall men'ibers depending from the under side of said plate,flap folders carried by the lower plate, a trap also carried by thelower plate, means rigidly connecting said two plates together andspaced apart so as to hold said walls and said flap folders in propercooperative position and whereby all of said parts are made toconstitute a single entity which may be inserted into or removed fromthe machine at will. and means whereby to detachably retain said entityin operative position within the machine.

In testimony whereof I aflix my signature in the presence of twowitnesses.

ADDISON E. AUGUSTINE.
